This is a thin-ground section of an ice core brought up from a depth of 114m. In polarised light, it shows the borders of ice crystals and gas bubbles.
In almost a decade of efforts by the team from the European Project for Ice Coring in Antarctica (EPICA), the Dome C ice core has enabled the reconstruction of Antarctic temperatures from the past 740,000 years. The results proof that CO2 concentration today is more than 28% higher than ever before during the last 800 000 years. The concentration of methane is today more than 124% higher than ever before during the analysed period.
